Who He Is: The German native is a model but perhaps best known as Olivia Palermo's other half.

What He Posts: Shots of his European vacations with Ms. Palermo in Greece, Germany and beyond, couple's snaps, modeling pics, and enough shirtless photos to fill every girl's quota and have any guy hitting the gym.
